Scientists Find New Path To Loss-Free Electricity
2014-02-14 12:49:57

Brookhaven National Laboratory Brookhaven Lab researchers captured the distribution of multiple orbital electrons to help explain the emergence of superconductivity in iron-based materials Armed with just the right atomic arrangements, superconductors allow electricity to flow without loss and radically enhance energy generation, delivery, and storage. Scientists tweak these superconductor recipes by swapping out elements or manipulating the valence electrons in an atom's outermost...

X-rays Reveal Another Feature Of High-temperature Superconductivity
2013-11-25 08:20:57

European Synchrotron Radiation Facility Discovery of a giant resonance puts these materials further apart Classical and high-temperature superconductors differ hugely in the value of the critical temperatures at which they lose all electrical resistance. Scientists have now used powerful X-rays to establish another big difference: high-temperature superconductivity cannot be accounted for by the mechanism that leads to conventional superconductivity. As this mechanism called...

Might it one day be possible to transmit electricity from an offshore wind turbine to land-based users without any loss of current? Materials known as "high temperature" superconductors (even though they must be maintained at -140°C!), which can conduct electricity without any losses, were supposed to make this dream a reality. But over the past twenty-five years, scientists have not been able to make any progress in this area. Research being done in EPFL's Laboratory for Quantum...

Scientists at the Naval Research Laboratory (NRL) have proposed theoretical models to explain the normal magnetic properties in iron-based superconductors. This research was published in the December 21, 2008 issue of Nature Physics. Their research builds on earlier research they conducted proposing a theoretical model for superconductivity in newly discovered iron-based superconductors. That earlier research was published in Physical Review Letters.To set the stage for the NRL researchers'...

The paper published in the Journal of the American Chemical Society (JACS) by a team led by professor Francesc Illas of the UB's Department of Physical Chemistry and director of the Laboratory of Computational Materials Science (CMSL) will help to broaden our understanding of the nature of superconducting materials and of the origin of the superconductivity phenomenon in high critical temperature materials. Other participants in the study are Ib©rio de P. R. Moreira (UB) and Jacek C....

Scientists at U.S. Department of Energy's Argonne National Laboratory used inelastic neutron scattering to show that superconductivity in a new family of iron arsenide superconductors cannot be explained by conventional theories.Funding for this research was provided by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences.  The mission of the Basic Energy Sciences (BES) program - a multipurpose, scientific research effort - is to foster and support...

Word of the Day
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
